Recent Codesys Safety Sil2 Security Vulnerabilities
Monitoring Access Race Condition in Unspecified Product
CVE-2026-79625
7.2 - High
- September 30, 2026
Affected products do not properly synchronize access to their monitoring functionality. When multiple clients send concurrent requests, this may lead to incorrect reads or writes, or to corruption of internal memory structures. An authenticated remote attacker with monitoring access can exploit this issue to cause incorrect data processing or a denial-of-service condition.
Race Condition
CODESYS Runtime: Unrestricted File Download via CmpApp (CVE-2023-37551)
CVE-2023-37551
6.5 - Medium
- August 03, 2023
In multiple Codesys products in multiple versions, after successful authentication as a user, specially crafted network communication requests can utilize the CmpApp component to download files with any file extensions to the controller. In contrast to the regular file download via CmpFileTransfer, no filtering of certain file types is performed here. As a result, the integrity of the CODESYS control runtime system may be compromised by the files loaded onto the controller.
